PACKING-RING FOR STEAM-ENGINES.

Application filed March 4, 1911.

Specification of Letterslatent.

Patented Nov. 28, 1911.

Serial No. 612,267.

To all whom it may concern:

Be it known that I, CHARLES H. ANDER- SON, a citizen of the United States, residing at Wolf Island, in the county of Mississippi and State of Missouri, have invented certain new and useful Improvements in Packing-Rings for Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to packing rings for steam engines.

My packing rings are especially designed for use around the piston rod where it passes through the end of the cylinder and through the partition in a multiple compartment cylinder. In engines of the last 1nentioned type, it is particularly desirable toprovide means for packing the joint around the piston rod in a durable and efficient manner in view of the difficulty in getting at this joint for inserting or renewing the packing.

It is my aim to provide an improved packing means which is durable, inexpensive to manufacture and easy to attach.

Other objects will become apparent from the following description.

The invention consists in the features of construction and combinations of parts hereinafter described, illustrated in the accompanying drawing and specified in the appended claims.

In the accompanying drawing illustrating the preferred embodiment of my invention: Figure 1 is a broken sectional view of a double compartment engine cylinder, showing my packing means in the head of the cylinder and also in the partition thereof. Fig. 2 is a cross section on the line w-w of Fig. 1 looking at the outer face of the partition. Fig. 3 is a sectional view on the line yy of Fig. 2, at right angles to the section on which Fig. 1 is taken, and Fig. 4 is a detail view of the packin rings.

Referring more particu arly to the drawing, 1 designates an engine cylinder which is divided into compartments 2 and 3. by the partition 4. The piston rod 5 passes through the cylinder head 6 and the partition 4, and is provided with two piston heads 7 and 8, respectively, operating in the compartments 2 and 3. My improved packing is placed in the cylinder head and partition around the piston rod.

The cylinder head and partition are each provided with a recess 9 entering from one side thereof and arranged concentrically of the opening through which the piston rod passes. These. recesses do not pass entirely through the head or partition, each being limited at its base by a flange 10 extending inward to the opening for the piston rod. Within each recess there are placed two concentric split rings 11 and12 of. suitable width to extend from thefiange at the base of the recess to a plane flush with the surface of the partition or piston head, as the case may be, on which the recessopens. The rings are retained in the recesses by plates 18 bolted or otherwise-secured to the partition and cylinder head.

At either side of the plate 13 and preferably arranged at right angles thereto in the partition and also in the cylinder head, there are two inclined grooves 14:. These grooves extend nearly to the bases of the recesses and serveto admit the steam to the recess around the outside of the rings whereby said rings are caused to shrink or contract around the piston rod with the result that a steam tight joint is made which effectually the cylinder head or from one compartment to the other of the cylinder through the partition. It will be noted that the split rings 11 and 12 break joints so that the steam cannot get through the slits therein.

It will further be observed that my packing means, as herein described, is very simple in construction, can be manufactured at a comparatively small cost and may be easily and quickly attached to an engine cylinder. The grooves, leading to the recess in which the rings are placed, may be formed in the cylinder head and partition with very little trouble and expense and their construction is such that they will not become filled or clogged up in use, which would'necessitate frequent repairs.

It should be understood that latitude is allowed for detail changes in the construction herein shown and described, as such changes may be made without departing from the spirit or sacrificing the advantages of my invention.

I claim:

1. In a steam engine cylinder, the combination, with the piston rod and cylinder head having a recess entering from one side thereof and arranged concentrically of the prevents the leakage of the steam through opening through which the piston rod passes, of packing rings mounted in said recess and extending from the base thereof to a plane flush with the surface on which the recess opens, and a plate extending across the openingof the recess for retaining said rings in place, said cylinder headbeing provided with a groove arranged at one side of said plate and leading into the recess from the surface of said cylinder head on which the plate is arranged, for the purpose specified.

2. In a steam engine cylinder, the combination, with the piston rod and cylinder head having a recess entering from one side thereof and arranged concentrically of the opening through which the piston rod passes, of packing rings mounted in said recess and extending from the base thereof to a plane flush with the surface on which the recess opens, and a plate extending across the opening of the recess for retaining said rings in place, said cylinder head being provided with a groove arranged at one side of said plate and leading into the recess from the surface of said cylinder head on which the plate is arranged and opening on the side of said recess for the purpose specified.

8. In a steam engine cylinder, the combination, with the piston rod and cylinder head having a recess entering from one side thereof and arranged concentrically of the opening through which the piston rod asses of ackin rin s mounted in said 7 p b recess and extending from the base thereof to a plane flush with the surface on which the recess opens, and a plate extending across the opening of the recess for retaining said rings in place, said cylinder head being provided with an inclined groove arranged at one side of said plate and opening on the side of said recess, the opening of said groove extending nearly to the base of the recess for thepurpose specified.

4. In a steam engine cylinder, the combination, with the piston rod and cylinder head having a recess'entering from one side thereof and arranged concentrically of the opening through which the piston rod passes, of packing rings mounted in said recess and extending from the base thereof to a plane flush with the surface on which the recess opens, and a plate extending across the opening of the recess for retaining said rings in place, said cylinder head being provided with oppositely arranged grooves at the sides of said plate and opening on the side of said recess for the purpose specified.

In testimony whereof, I affix my signature, in presence of two witnesses.

CHARLES H. ANDERSON.
